Heat shield protection
Genuine Porsche rear bumper guard plate for 911 GT3 and GT3 RS. Installed near the exhaust system, it separates the surrounding bumper components from a concentrated source of heat.
Fits
- Porsche 997.1 911 GT3 2006–09
Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
The plate forms part of the protective arrangement within the GT3 rear bumper assembly. Its position helps control the transfer of heat from the nearby exhaust area to adjacent bumper materials and components.
Functions
- Provides a physical barrier between the exhaust area and bumper assembly
- Helps manage heat around neighbouring rear body components
- Supports the original protective layout of the GT3 rear bumper
- Replaces a missing, corroded or distorted guard plate
Technical Details
- Manufacturer: Porsche
- Part number: 99750581192
- Component type: Guard plate and exhaust heat shield
- Installation position: Rear bumper area
- Application: Porsche 997.1 911 GT3 and GT3 RS
- Model period: 2006–09
Symptoms of Fault
- Visible cracking, distortion or corrosion
- Guard plate missing following bumper or exhaust work
- Rattling or buzzing caused by loose mounting points
- Heat discolouration or marking on nearby bumper components
- Damaged fixings preventing the plate from sitting securely
Why Replacement Matters
A damaged or absent plate can leave nearby bumper materials more exposed to heat from the exhaust area. Replacing it restores the intended barrier and helps maintain the factory arrangement. The mounting hardware, adjoining shields and exhaust alignment should also be inspected during fitting, as loose fixings or incorrect exhaust clearance can cause vibration and unwanted heat exposure.
FAQs
- Where is this guard plate fitted?
It is positioned within the rear bumper assembly close to the exhaust system. - Is this an exhaust component?
It is a protective guard plate associated with the exhaust area rather than a gas-carrying section of the exhaust system. - Can a damaged plate cause a rattle?
Yes. Corrosion, distortion or damaged mounting points can allow the plate to vibrate, particularly at certain engine speeds. - Does it fit every Porsche 997?
The supplied application is for the 997.1 911 GT3 and GT3 RS. Confirm the part number against the vehicle details before installation.
